Environmental Contaminant Standards - New Products
ShareFollowing please find a listing of new items that became available from CIL since the first quarter of 2022. Updates are being released on a quarterly basis as CIL adds new products for environmental analysis to our inventory. Each part number is a link to the full product listing on the CIL website. In the case of mixtures, a “components and concentrations” file is part of the product listing, as located under the “SDS and Product Documents” portion of the item page. Most items included in these updates are in stock at CIL and available for standard delivery, but please contact CIL for complete product availability.

PER- AND POLYFLUOROALKYL SUBSTANCES (PFAS)
Increased interest in short and ultra-short chain PFAS has led to new developments at CIL, including the introduction of C3 carboxylic acid PFPrA. DONA is now available as the free acid, while PFAS EF-28 and Superfund native mixtures have been updated to include components now in the sodium salt form. Please note these mixtures are still formulated such that the target concentration is based on the free acid analyte. CIL has formulated the US EPA Method 8237 native mixture and should soon also have the Method 8327 labeled mixture (comparable to PFAC-24PAR and MPFAC-24ES respectively). New efforts have led to the development of small chain perfluoro mono-ether acids PMPA and PEPA. Read more about CIL’s PFAS standards here.

6PPD-Quinone, which is an ozonation byproduct of rubber tire additive 6PPD, has been shown to be highly toxic to Coho salmon. CIL initially developed a phenyl-13C6-labeled standard to assist researchers with their testing needs and has most recently added a new 13C12-labeled standard to its product offerings. The two labeling options can be used in combination to offer further improvement of precision for quantitative analysis. Read more about 6PPD-Quinone and CIL’s standards here.
| Part number | Description | Concentration |
| CLM-11290-1.2 | 6PPD-Quinone (ring-13C12, 99%) CP 95% | 100 µg/mL in acetonitrile |
Tetrahydrocannabivarin (THCV) is the latest cannabinoid to be added to CIL’s line of cannabis standards. THCV is a homologue of tetrahydrocannabinol (THC) and does not exhibit psychoactive effects. It has potential use for weight loss and/or management of obesity and type 2 diabetes, as it has been shown to suppress the appetite and increase satiety.1 For a complete listing of CIL’s cannabis testing standards, please click here.
| Part number | Description | Concentration |
| DLM-10707-1.2 |
Tetrahydrocannabivarin (THCV) (propyl-3,3,3-D3, 98%) |
100 µg/mL in methanol |

Terephthalate esters have been gaining use as phthalate replacement products as increased scrutiny and restrictions on phthalates occur. CIL has previously synthesized and offered mono-2-ethylhexyl terephthalate standards for human exposure studies and has recently produced a standard for the native parent compound, bis(2-ethylhexyl) terephthalate. Read more about CIL’s full line of phthalate and phthalate-related compounds here.
| Part number | Description | Concentration |
| ULM-11303-1.2 | Bis(2-ethylhexyl) terephthalate (unlabeled) | 100 µg/mL in MTBE |
