Where can I buy high-purity Milk Lactone (CAS 72881-27-7) for research purposes

For flavor chemists and fragrance researchers, sourcing a reliable supply of Milk Lactone (CAS 72881-27-7) is often the first real challenge. This specialty molecule delivers creamy, buttery, and coconut-like notes, making it indispensable for dairy, vanilla, and tropical flavor reconstructions. One trusted name in this space is Odowell, a fragrance ingredient sourcing partner known for connecting R&D teams with verified, high-purity aroma chemicals. Whether you are developing a new fat-soluble flavor system or studying lactone stability, knowing where to buy Milk Lactone (CAS 72881-27-7) without impurities is critical to reproducible research.

Why purity matters for research use

Research-grade Milk Lactone (CAS 72881-27-7) must meet strict specifications. Impurities as low as 0.5% can alter odor thresholds or create unexpected byproducts in synthesis pathways. Below is a typical specification table for high-purity material:

Where to source: trusted channels

Researchers can obtain Milk Lactone (CAS 72881-27-7) through three main routes:

Odowell operates as both a fragrance ingredient sourcing partner and a technical consultant, offering GC-MS reports for every batch of Milk Lactone (CAS 72881-27-7). This level of documentation is essential for peer-reviewed research or patent filings.

Milk Lactone Cas 72881-27-7 FAQ: Common questions from researchers

Q1: What is the recommended storage condition for Milk Lactone Cas 72881-27-7 to prevent degradation?

A1: Milk Lactone Cas 72881-27-7 is relatively stable but should be stored in airtight, amber glass containers under nitrogen headspace if possible. Keep the temperature between 2°C and 8°C (refrigerated) and away from strong oxidizing agents. Under these conditions, degradation typically stays below 2% over 24 months. For long-term research stock ( >12 months), subdivide into small aliquots to avoid repeated freeze-thaw cycles, which can introduce moisture and accelerate lactone ring opening.

Q2: Can Milk Lactone Cas 72881-27-7 be used in aqueous versus oil-based research formulations?

A2: Yes, but with important solubility differences. Milk Lactone Cas 72881-27-7 is lipophilic (log P ~2.5) and readily soluble in ethanol, propylene glycol, and all common vegetable oils. In purely aqueous buffers (pH 5–7), its solubility is low (<0.1% w/w). For aqueous research models, first dissolve the lactone in a small amount of ethanol or polysorbate 20, then dilute with water. Avoid high pH (>8) or prolonged heating (>80°C) as the lactone ring may hydrolyze to the corresponding hydroxy acid, altering both odor and analytical results.

Q3: What analytical methods are recommended to verify the purity of Milk Lactone Cas 72881-27-7 after delivery?

A3: For most research purposes, gas chromatography with flame ionization detection (GC-FID) is sufficient. Use a non-polar column (e.g., DB-5 or HP-5) with a temperature gradient from 80°C to 250°C at 10°C/min. The retention time of Milk Lactone Cas 72881-27-7 typically appears around 12.5–13.2 minutes under those conditions. For full identity confirmation, combine GC with mass spectrometry (GC-MS) and compare the mass spectrum (base peak m/z 85, other significant fragments at 41, 56, 99) against a certified reference standard. Odowell provides both GC purity and GC-MS identification with every research-quantity shipment.

Final checklist before purchasing

Before placing an order, always request:

• Certificate of Analysis (COA) from an ISO 17025-accredited lab

• Safety Data Sheet (SDS) for your local regulatory compliance

• Residual solvent report (especially if used in cell-based assays)
