Ion-pairing reagents, when used as mobile phase additives, promote the analysis of ionic and highly polar substances on reversed phase HPLC columns. The purity of mobile phase additives is of highest significance for their effective application. Sigma-Aldrich makes available a variety of tailor-made reagents for anionic (quaternary ammonium and phosphonium salts) and cationic (alkanesulfonates) separations. All mobile phase additives are tested thoroughly with special consideration on the demands of modern reversed phase HPLC:

Tetramethylammonium chloride (TMAC) is structurally similar to alkyltrimethylammonium salts. Oxidation of TMAC yields formaldehyde and trimethlamine. It is considered as poor phase-transfer catalyst for most reactions as it is insoluble in organic media. However, it is highly suitable as phase-transfer catalyst for fluorination of chlorobenzaldehydes along with alkali metal fluorides which yield 1,2,2,2-tetrafluoroethyldifluoromethyl ether.

Tris (2-carboxyethyl) phosphine (TCEP) is very effective in cleaving disulfide bonds in aqueous solution. It dissolves in water and is odorless, unlike other trialkylphosphines (tributylphosphine). It is also less toxic than 2-mercaptoethanol. These advantages make it better than the other reducing agents.
It belongs to the trialkylphosphine class.

Tris(2-carboxyethyl)phosphine hydrochloride solution

Empirical Formula (Hill Notation):	C₉H₁₅O₆P · HCl
CAS Number:	51805-45-9
Molecular Weight:	286.65
MDL number:	MFCD00145469
PubChem Substance ID:	24883469
NACRES:	NA.25

Tris (2-carboxyethyl) phosphine (TCEP) can be used in several downstream applications including SDS-PAGE, mass spectrometry, labeling with cysteine specific tags, and modification of cysteine containing compounds. It prevents oxidation of protein samples, which makes it a useful buffer component as it helps to preserve enzymatic activity. It has been used in the reduction and measurement of glutathione.
Tris (2-carboxyethyl) phosphine (TCEP) has also been used:

to cleave cysteine residues in a synthetic peptide
in reduction buffer for RNA Sequential Probing of Targets (SPOTs) imaging
for the reduction of oligonucleotides
as reducing agent during mitochondrial isolation

Tris(2-carboxyethyl)phosphine hydrochloride solution reduces the disulfide bonds and leaves other functional groups intact in proteins.
As a non-mercaptan reducing agent, it avoids the toxicity inherent in thiol-containing compounds. It is capable of disrupting the botulinum neurotoxin B heavy-chain/light-chain complex that is held together by a single disulfide bond, and that is responsible for endocytosis, and ultimately the toxicity, of the toxin. Since disulfide-coupled subunits are characteristic of many toxins (e.g., ricin, snake venom, and all BoNT serotypes), it may be useful as a rescue prophylactic in cases of toxin administration.
