PER- AND POLYFLUORINATED SUBSTANCES (PFAS)
Tetrafluoro-2-(heptafluoropropoxy) propanoic acid, or more commonly “HFPO-DA” or “GenX” is the dimerized product of a fluorinated ether compound developed as a replacement for PFOA. Extensive use of the fluoropolymer, and subsequent identification in numerous water sources has led to extensive research on this compound. As CIL continues to complete labeled and unlabeled PFAS individual standards we are now able to prepare more extensive PFAS mixtures for both regulatory methods and custom projects. CIL is pleased to introduce U.S. EPA Method 537 (original version) standard mixtures. Look for the revised Method 537.1 mixtures in the near future.

NITROSAMINES
N-Nitroso-N-methyl-4-aminobutyric acid (NMBA) has recently been detected in the blood pressure medicines Losartan and Irbesartan, which were initially recalled along with Valsartan due to the presence of related compounds N-Nitrosodimethylamine (NDMA) and N-Nitrosodiethylamine (NDEA). CIL has historically offered standards for NDMA and NDEA, and recently synthesized NMBA standards in response to the need for analyzing this third probable carcinogen detected in popular blood pressure medicines.
