Chemical Structure

3,5-di-tert-butylsalicylic acid CAS 19715-19-6 chemical structure

Description

3,5-di-tert-butylsalicylic acid (CAS 19715-19-6), molecular formula C15H28O3 and molecular weight 256.38 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 3,5-di-tert-butylsalicylic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 256.38 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
