Description

5137-70-2 Dodecylphosphonic acid Phosphonic acid, dodecyl- Phosphonic acid, P-dodecyl- 4-04-00-03565 (Beilstein Handbook Reference) BRN 1778341 Dodecane phosphonic acid n-Dodecanephosphonic acid 1-Dodecanephosphonic acid n-Dodecyl phosphonic acid n-Dodecylphosphonic acid EINECS 225-897-8 NSC 407872 (CAS 5137-70-2) is a high-purity analytical reference standard with the molecular formula C12H27O3P and a molecular weight of 250.31 g/mol.

Structurally, 5137-70-2 Dodecylphosphonic acid Phosphonic acid, dodecyl- Phosphonic acid, P-dodecyl- 4-04-00-03565 (Beilstein Handbook Reference) BRN 1778341 Dodecane phosphonic acid n-Dodecanephosphonic acid 1-Dodecanephosphonic acid n-Dodecyl phosphonic acid n-Dodecylphosphonic acid EINECS 225-897-8 NSC 407872 (C12H27O3P) contains a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of -0.5, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 250.31 g/mol, it falls into the medium-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.

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.

As a certified reference material (CRM), 5137-70-2 Dodecylphosphonic acid Phosphonic acid, dodecyl- Phosphonic acid, P-dodecyl- 4-04-00-03565 (Beilstein Handbook Reference) BRN 1778341 Dodecane phosphonic acid n-Dodecanephosphonic acid 1-Dodecanephosphonic acid n-Dodecyl phosphonic acid n-Dodecylphosphonic acid EINECS 225-897-8 NSC 407872 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.
