Chemical Structure

LAS Solution, 1,000 mg/L, 25 ml CAS 42615-29-2 chemical structure

Description

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

LAS Solution, 1,000 mg/L, 25 ml (CAS 42615-29-2) is a high-purity analytical reference standard with the molecular formula C18H29O3SNa and a molecular weight of 348.48 g/mol.

Based on its molecular formula C18H29O3SNa, LAS Solution, 1,000 mg/L, 25 ml contains a steroid core, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 348.48 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
