1,3-Distearoyl-2-Chloropropanediol-d5
Trace analysis of chloropropanol fatty acid esters in edible oils needs an internal standard that survives hydrolysis, derivatisation and clean-up alongside the analyte. 1,3-Distearoyl-2-Chloropropanediol-d5 is the deuterium-labelled diester form of 2-MCPD, carrying five deuterium atoms on the chloropropanediol backbone. Because the label is introduced at the start of the workflow, results stay comparable from batch to batch and between operators. Laboratories spike it into samples before ester cleavage, then determine the released 2-MCPD against the labelled signal, correcting for losses during extraction and derivatisation and supporting peak assignment in GC-MS/MS and LC-MS/MS procedures. It is a white solid of formula C39H70D5ClO4 and molecular weight 648.49, with pack sizes listed between 1 mg and 100 mg. Store at -20 +/- 5 C and ship with ice packs. Enquiries about quotations, specifications or documents are welcome.
