1,2-Dipalmitoyl-<I>sn</I>-glycerol-3-phosphate sodium salt CAS 105381-36-0

Description

The occurrence of 1,2-Dipalmitoyl-<I>sn</I>-glycerol-3-phosphate sodium salt is closely related to a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1,2-Dipalmitoyl-<I>sn</I>-glycerol-3-phosphate sodium salt (CAS 105381-36-0), molecular formula C35H67O8PNa and molecular weight 669.88 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, 1,2-Dipalmitoyl-<I>sn</I>-glycerol-3-phosphate sodium salt is typically white to off-white amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 669.88 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
