Benzaldehydepropyleneglycolacetal; 98% stands out as a specialized organic compound derived from the reaction between benzaldehyde and propylene glycol. This reaction forms a colorless to pale-yellow liquid under typical laboratory and industrial conditions. The chemical formula, C13H18O3, points to its structure as an acetal, which incorporates the aromatic benzaldehyde core and two adjacent ether linkages from the glycol. The product reaches the market at a purity of 98%, making it suitable for precise chemical synthesis, fragrance work, and research.
This compound sits at a molecular weight of roughly 222.28 g/mol. The density, an important property for process engineers, generally hovers around 1.08 g/cm3 at 20°C, which gives a useful marker for those handling it in bulk or calculating dilutions. Its liquid form simplifies mixing and transfer, avoiding the clumping challenges seen with powders or the slow dissolution of crystals. With a moderate boiling point, often in the range of 120-150°C under reduced pressure, its use in controlled distillation or solvent replacement comes into play without requiring extreme temperatures. Benzaldehydepropyleneglycolacetal's chemical structure features the classic aromatic ring associated with aldehydes, but protection as an acetal gives it stability against nucleophilic attack, increasing the shelf life and handling safety compared to unprotected benzaldehyde.
Producers typically supply benzaldehydepropyleneglycolacetal; 98% in liquid form. It flows easily, stays clear in pure conditions, and emits an odor reminiscent of bitter almonds due to the benzaldehyde fragment. Suppliers occasionally provide it in small solid pearls or flakes if formulated in a different physical form for niche applications, but most buyers come across a clear or slightly viscous liquid packed in glass or high-density polyethylene bottles. Being a liquid cuts waste in measuring and reduces residue, important for anyone who relies on batch reproducibility or automated addition systems. Crystals form only under low temperatures or through intentional solvent evaporation, but this isn’t common in daily operations.
Within the context of global trade, importers look for the HS Code associated with this compound. Benzaldehydepropyleneglycolacetal; 98% falls under HS Code 2913000090, classifying it alongside acyclic aldehydes and their derivatives. Specifications run beyond purity and appearance, stretching to water content, acid value (to assure low free acid), and color index. These parameters make sense for manufacturers aiming at consistency, especially in pharmaceutical or fragrance industries, where even a minor deviation changes the performance or sensory profile. Reliable suppliers document every batch with certificates of analysis, recording tested values rather than just advertising typical figures.
Chemical safety always stays top of mind. With benzaldehydepropyleneglycolacetal, direct skin or eye contact can cause irritation, while inhaling high concentrations of vapor may lead to discomfort or headaches. This material stores best in cool, ventilated spaces, away from strong acids or oxidizers, preventing unwanted side reactions or decomposition. Fire risk doesn’t climb as quickly as with more volatile organics, but prudent operators fit storage areas with spill control and ventilation. Labeling stays essential—I’ve seen workplace mishaps avoided simply because every bottle, drum, and container sports clear hazard symbols and all workers get regular training. Standard personal protective equipment includes nitrile gloves, goggles, and lab coats. As regulations get stricter, many facilities add secondary containment for larger drums to catch accidental leaks.
People use benzaldehydepropyleneglycolacetal; 98% chiefly as a raw material in organic synthesis. The protected aldehyde group allows stepwise reactions where you don’t want the aldehyde to react prematurely—this matters when building complex molecules in pharmaceutical or flavor chemistry. In perfumery, this acetal gives stability and subtle aromatic nuances that expand both top and heart notes. I’ve watched creative chemists in flavor labs assemble compounds like this one into unique, food-safe scents, because the acetal linkage resists breakdown during processing or storage. Specialty resin manufacturers sometimes include benzaldehydepropyleneglycolacetal for its blendability and mild solvency, tuning the physical properties of their polymers.
No compound gets a free pass on environmental checks. Waste processors must capture spent solutions and contaminated wipes, funneling them through licensed chemical disposal streamlines, so surface and groundwater stay uncontaminated. While benzaldehydepropyleneglycolacetal doesn’t carry the heavy toxicity of halogenated solvents or some heavy metals, it still calls for mindful storage and disposal. Workers handling liter quantities or more should routinely check for signs of vapor accumulation in enclosed spaces, using simple gas detection tubes or electronic monitors. Plant managers invest in employee medical monitoring to catch chronic exposure risks before these turn into problems.
One path forward means designing production facilities to reclaim and recycle solvents whenever possible, cutting raw material use and emissions. Tight inventory tracking ensures first-in, first-out rotation, so nothing sits too long or degrades into hazardous byproducts. Advances in green chemistry keep nudging users toward lower-impact reagents, though acetals like benzaldehydepropyleneglycolacetal still offer unmatched protection during complex syntheses. Ongoing research into biodegradable alternatives could someday yield replacements for petroleum-derived glycol fragments, easing disposal challenges and lowering the product’s carbon footprint. Chemists also run life-cycle studies to understand the true environmental cost, which can spark supplier partnerships for shared stewardship.
Benzaldehydepropyleneglycolacetal; 98% brings together unique aromatic properties, stable chemical protection, and versatile industrial utility. With solid handling protocols, responsible waste management, and a close eye on purity and safety specs, experts in fragrance, pharmaceutical, and specialty chemical industries keep benefiting from its distinctive offerings while minimizing risk to people and planet. Staying updated on regulatory trends and innovations helps shift both science and industry toward safer, more sustainable choices.
