Chemical Structure
Description
CATO supplies Polysulfide in light mineral oil (CAS 68425-16-1), a certified reference material (molecular formula C18H38S3, MW 350.69 g/mol) for analytical method development and quality control.
Structurally, Polysulfide in light mineral oil (C18H38S3) contains sulfur-containing functionality. The molecule exhibits a degree of unsaturation (DBE) of 0.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 350.69 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.
As a certified reference material (CRM), Polysulfide in light mineral oil meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
