(2R,3R,4E)-2-Amino-3-hydroxy-4-octadecenoic Acid Ethyl Ester Hydrochloride 355803-79-1 Ethyl trans-D-Erythro-2-amino-3-hydroxy-4-octadecenoate Ethyl-D-erythro-sphingosinate Hydrochloride CAS 355803-79-1

Description

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.

(2R,3R,4E)-2-Amino-3-hydroxy-4-octadecenoic Acid Ethyl Ester Hydrochloride 355803-79-1 Ethyl trans-D-Erythro-2-amino-3-hydroxy-4-octadecenoate Ethyl-D-erythro-sphingosinate Hydrochloride (CAS 355803-79-1), molecular formula C20H39NO3HCl and molecular weight 377.99 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, (2R,3R,4E)-2-Amino-3-hydroxy-4-octadecenoic Acid Ethyl Ester Hydrochloride 355803-79-1 Ethyl trans-D-Erythro-2-amino-3-hydroxy-4-octadecenoate Ethyl-D-erythro-sphingosinate Hydrochloride (C20H39NO3HCl) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 377.99 g/mol, it falls into the moderately-high-molecular-weight range. 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.
